The invention consists in the foregoing and also envisages constructions of which the following gives examples.

A preferred form of the present invention will now be described with reference to the accompanying drawings in which;

FIG. 1 is a plan view of one form of a container in accordance with the present invention showing a generally square or rectangular form insofar as external periphery is concerned but showing two receptacles, the smaller one being suitable, by way of example, for retaining yoghurt and the larger being suitable for retaining, for example, a breakfast cereal [or alternatively the smaller suitable for retaining a cream or milk product while the larger retains a breakfast cereal, or one containing a puree with the other a cereal or yoghurt, etc.],

FIG. 2 is a diagrammatic side elevation arrangement at section “AA” of the arrangement of FIG. 1, ie; looking normally of the longitudinal axis of the spoon which is the preferred eating or mixing utensil and looking towards the bowl of the spoon, the bottom surface of which is seen protected (but uncovered) between the two receptacles,

FIG. 3 is a plan view of the spoon handle detail at the region of the broken circle as depicted,

FIG. 4 is a scrap section at “BB” with respect to FIG. 3,

FIG. 5 is a scrap section at “CC” with respect to FIG. 3,

FIG. 6 is a bottom view of an alternative form of the package wherein an additional cover providing means is provided enveloping and enclosing the underside of the utensil,

FIG. 7 is a scrap section at “DD” with respect to FIG. 6,

FIG. 8 is a scrap section at “DD” with respect to FIG. 6, wherein instead of the foil being affixed to the underside of the package, it is moulded as part of the package to form a hollow for the utensil to sit in,

FIG. 9 is a scrap section at “DD” with respect to FIG. 6 wherein the tray is frangible through its centerline,

FIG. 10 is a bottom perspective view of a preferred form of the present invention illustrating on the larger of the two receptacles the wedge providing members,

FIG. 11 is a plan view of an alternative configuration of a package of the present invention in an uncovered configuration, and

FIG. 12 is a view in direction “A” of the package of FIG. 11.

In the preferred form of the present invention the receptacle 1 is formed by either injection moulding or more preferably from a vacuum moulding procedure from a feedstock of an appropriate food grade plastics material such as about 1 mm thickness of polystyrene.

The reference to “vacuum” moulding or forming herein refers to the application of a pressure differential between one and the other side of the web of sheet thermoplastic material from which the pack/tray of the present invention is formed, whether it is a positive pressure on the side of the web material from which the web material forms into the mould or whether it is a low pressure (vacuum) on the other side to draw the web of material into the mould in order to form the pack/tray. It may even indeed be the combination of both.

As can be seen in the preferred form of the present invention there are a plurality of receptacles with receptacle 2 and receptacle 3 being shown of two different sizes and disposed diametrically apart with respect to the outer periphery.

The outer periphery 4 in the preferred form of the present invention includes a rim region 5 surrounding the receptacle 2 and a rim region 6 that surrounds the receptacle 3 and such rim regions (even if strengthened by contouring) are preferably generally coplanar. Interposed between the two rim regions is preferably a hinge axis 7 and on that axis is preferably the preferred eating and/or mixing utensil 8 which includes a bowl 9.

Overlaying the filled receptacles 2 and 3 only after the container has been presented to appropriate filling stations is a foil or web of appropriate plastics material that is preferably sequentially applied from container to container and is preferably welded or otherwise adhesively fixed to said rim surface(s).

Shown in FIG. 1 is a direction of extrusion of the material from which the container is vacuum or otherwise moulded in the preferred form. The direction of extrusion on the drawing is shown to indicate the alignment of the machine direction of the extruded sheet. The sheet is easy to shear along the machine direction and difficult to shear across the machine direction, such that if the orientation of the spoon and hinge area is across the machine direction, it is likely that the spoon would be in two pieces rather than one after removal. Shown as 10 in dotted outline in FIG. 2 the film or foil material 10 which overlies both receptacles 2 and 3 and any contents contained therein (not shown in FIG. 2) as well as the upper surface of the utensil 8. Such foil (aluminium or composite) or plastics film (or composite) 10 is preferably affixed by heat seal lacquer adhesive.

In less preferred forms the film cover can be extruded direct on to the rims while hot or a tacky foil process used.

This pack is generally used as a two part pack for yoghurt and cereal type products, the yoghurt being in the larger pocket and the cereal in the smaller pocket.

In addition to the preferred form of the invention as describe above, the package may also be provided with a cover providing means as shown in FIG. 6.

Preferably the cover providing means envelops the bottom of the spoon (when in a non-separated condition) and provides a protective layer to the underside of the utensil. Most preferably the cover providing means 20 is affixed to the package as a subsequent process after the packages shown in FIGS. 1-5 has been formed. Preferably it is located about the peripheral region of the utensil 8. Preferably such location is to the rim regions 5 and 6 on each side of the hinge axis 7.

Most preferably the cover providing means is a foil seal and is fitted as a secondary process to the rim regions 5 and 6 by suitable adhering means such as heat sealing, RF sealing, ultra sound, welding, or suitable adhesive sealing at points 21. Most preferably the foil seal is preshaped to correspond to the bottom surface(s) of the spoon (or utensil) and is adhered to the package most preferably continuously about its perimeter. However such sealing may be of a discontinuous nature around the perimeter. The foil need not necessarily be preshaped and may have sufficient flexibility to conform to the desired shape.

Alternatively as shown in FIG. 8 there is provided and moulded as part of the package, a receptacle region of a hollow or depressed nature or the like for receiving a separate utensil such as a spoon. In this preferred form the receptacle region is shaped suitably to receive the utensil and may be frangible about the periphery thereof at 23. Alternatively the frangible region may be along the centerline as shown in FIG. 9 along 24. Such frangible region(s) shown in FIGS. 8 and 9 may (a) provide access to the utensil though the bottom of the package but are/is preferably there to (b) allow the package to be bent so that the content of one tray is able to be emptied into the other. In some yet other forms of the present invention a sprayable composition can be provided after the forming of the tray to the underside of the utensil.

The tray of the present invention is preferably adapted to be stackable with like adjacent trays to allow for stacking for filling, transportation or other like reasons. FIG. 10 shows a further embodiment of the present invention where at least the big receptacle has the stack supporting shoulder 25 having provided thereunder a chamfer 26 (or wedge providing means) which will provide a wedging effect occurs to ensure a positive placement of each shoulder 25 on a rim region of the like container thereunder in a stack.

Where as depicted in FIG. 10 there are a plurality of receptacles such a chamfer can, if desired, be provided on each of the stack indexing features but not necessarily so provided there is at least in respect of one of the receptacles, preferably a positive location horizontally of a container or tray in the stack.

Also within the scope of the present invention is the provision of a plurality of utensils on or in a single tray or container, preferably each of which is frangible although not necessarily so. Some can, if desired, be located within a recess underlying the foil or cover for the receptacle or receptacles of the tray or extensions thereof. In addition the present invention also envisages a tray having a single receptacle as shown in FIGS. 11, and 12.

To enable the product to be better utilised as a snack food, it is desirable to include a spoon at the point of manufacture.

This tray includes a spoon formed into the dividing surface between the two receptacles. The spoon is nearly completely cut out from the top surface of the tray expect for two retainer areas placed at the midpoint of the spoon at either side of the handle. These areas are not completely cut and retain the spoon to the tray.

The top of the tray is covered by a foil or web like material which is heat sealed around each pocket, also covering the top face of the spoon.

The consumer peels the foil from the pack, then pushes down on the bowl end of the spoon, this causes the spoon to pivot around the retentions at the midpoint. This action also propagates a split in the retention area parallel to the handle of the spoon due to the retentions being aligned with the direction of orientation of the sheet. (manufacturing machine direction).

The spoon is then grasped by the upward standing handle and removed from the pack with a twisting action.

The pack can also be bent along the hinge line to tip the contents of the smaller bowl into the larger bowl should the customer so desire. It is also possible to separate the large and small bowl in this manner if so desired. Along the hinge axis which preferably has a line (whether continuous or not) along at least part of the axis.

The primary advantage is that this pack can be made in a single manufacturing operation in a single or multistage thermoformer (although more suited to a single stage thermoformer).

The current packs on the market which include a spoon utilise a separate spoon which must be fitted to the tub in a separate ancillary operation. These ancillary operations are expensive in terms of unit cost and capital requirements for assembly machines.

They also add significantly to the ongoing costs of the product and require longer lead times to manufacture as the multistage process takes more time to produce a finished product than a single stage process.

Approximate capital requirements for the separate spoon and tub system are in the order of 1996 NZ$350,000.00 to purchase tooling for the spoon, tub, and an assembly machine, commissioned, ready to run. Capital requirements for the single stage process “spoonpak” product are in the order of 1996 NZ$65,000.00.

Features of Importance in the Preferred Forms Include

1. Single or multistage manufacture of a pack with a removable shaped spoon (or other utensil from a single sheet of feed stock using the thermoforming process.

2. The incomplete cutting out of the spoon at the midpoint being used to retain the spoon in the pack until the end user removes it.

3. The alignment of the direction of extrusion of the sheet parallel with the side of the handle to enable the thermoplastic polymer cleanly shear out when the spoon is twisted out after depressing the bowl area inwardly.

4. The improvement of the performance of the hinge area of the container by the removal of the centre area, being the spoon. The current products are nearly impossible to bend along the intended hinge line, whereas this product has a significantly smaller hinge area, able to flex easily and also to be fully separable if desired.
